M20 Concrete: Step-by-Step Guide to Material Calculation
M20 is the most commonly used concrete grade in residential construction. This article shows you exactly how to calculate the quantity of cement bags, sand, and coarse aggregate needed — with a full worked example. What is M20 Concrete? M20 concrete has a mix ratio of 1:1.5:3 (Cement : Sand : Coarse Aggregate) and a characteristic compressive strength of 20 N/mm² at 28 days. It is widely used…
